Rainforests February 18th‚ 2013 Mr. Zanardo AJ D’Orazio CGF 3M Grade 11 Rainforests are the oldest living ecosystems on earth. They only cover about 6% of the Earth surface but they contain more than half of the world’s animal and plant species. Rainforests are described as a tall but dense jungle. It is called a “rain” forest because of the high amount of rainfall it gets per year. There are two different types of rainforests Tropical and Temperate. A tropical rainforest is located

chains. The starting point of a food chain is a category of organisms called producers. Producers are‚ in fact‚ plants. So‚ we can say that all the food chains begin with a green plant (or grass) which is the original source of all food. Let us take an example to understand the meaning of food chain. Suppose there is a field having a lot of green plants (or producers of food). Now‚ plants can be eaten up by a rat. The rat‚ in turn‚ can be eaten up by a cat. And finally‚ the cat can be eaten up by

fit in Kappmeyer’s upgrade of the Mon Valley plant due to physical locations‚ feasibility‚ quality and other factors. But the CSP technology has shown improvement and with more R&D‚ CSP will surpase the conventional technology in the future. Capital costs were going to lowered from $1000 to $300 which would decrease USX’s costs in the future and hence increase profits. Instead of combining the plan of adoption of CSP and upgrade of the Mon Valley plant‚ USX should think about investing in CSP technology

reduce their health‚ their rate of growth and reproduction. The largest and healthiest populations of species will occur when conditions are within the optimal range. for example‚ water is an important source of life for all plants. In disturbed area water may be less‚ so plants may not grow as much as hillside with more water. Also‚ strong winds can pull out some of trees in a specific habitat‚ and that will make the habitat more disturbed‚ but on the other hand‚ the habitat that did not expose to

hyrdrosere is a plant succession which occurs in a fresh water lake. In time an area of open fresh water will dry out forming woodland. During a hydrosere there are many abiotic factors that change‚ which causes different species to inhabit the lake depending on the conditions they need to thrive and live successfully. There are many different stages that occur during a hyrdrosere the first stage introduces a pioneer species. A pioneer species is usually a community of hearty plants with adaptations

ABSTRACT EXAMPLES Writing an Abstract – Examples Each student who completes a science fair project must write an abstract to be displayed with the project. An abstract gives the essence of the project in a brief but complete form — it should not exceed 250 words. Judges and the public should have a fairly accurate idea of the project after reading the abstract. The abstract must focus on the current year’s research and give only minimal reference to previous work. Details and discussions should

1. Name and describe the life cycle of plants. The plant life cycle is consisted of two parts: the gametophyte phase where it produces gametes by mitosis and the sporophyte phase which produces spores by meiosis 2. Contrast the life cycle of plants to that of animals: Typical life cycle: alteration of generation (plants)‚ diploid (animals) Resulting structure from meiosis: spores-plants‚ gametes-animals Occurrence of mitosis: gamete production-plants‚ zygote to individual-animals 3.

The rate of photosynthesis in each of the beakers will depend what is wrapped around the beakers such as red and blue cellophane‚ as well as the control of the experiment the beaker without cellophane. The cellophane will directly impact the light getting absorbed as well as the amount of CO2 in the beakers. Which overall as result will determine the final color of the water mixed with bromothymol blue. What was being measured was the color of the water after CO2 has been blown in the beakers. The

Review Questions 3. Animals benefit from the relationship with plants because they are able to get rewards such as pollen and nectar. With these they have the ability to continue on with their daily work. Applying Your Knowledge 1. The rise in prominence of one major group does not necessarily result in the total replacement of a previously dominant group because one group may work better in the part than the other group. Gymnosperms for example produce excess amount of pollen‚ they are
